BTC Summer ranging

Today is the first day of Summer 2017, the past two summers Bitcoin has ranged in a sideways pattern from June 21 to September 21 before breaking upwards later in the Fall. I suspect there's a better than even chance this pattern repeats as accumulation takes place over the summer before taking off again this fall. If this pattern does repeat I would expect the swings to be proportionally larger because the size of the market has grown just as the swings of 2016 were larger than the swings of 2015. Profit can still be made or lost in a sideways market, both Bitcoin and Altcoins. I hope everybody has a profitable summer (In the Northern Hemisphere).
